TOOL FOR JOINING BICYCLE-TUBES.

SPECIFICATION forming part of Letters Patent No. 611,802, dated October4, 1898. Application led February 17, 1897. Serial No. 623,880. (Nomodel.) Patented in England January 19,1897, No. 1,410.

To @ZZ whom, it may concern.-

Be it known that I, EDWIN TAYLOR,stamper and piercer, a subject of theQueen of Great Britain, residing at 1 Alfred street, I/Varstone lane,Birmingham, in the county of Warwick, England, have invented certain newand useful improvements'in tools for forming the junctions of tubes ormembers in building cycles and motor-car frames and the like, by whichmeans I can easily and expeditiously expand the tubes so as to securelyhold them in` their sockets or junctions without the use of solder orbrazing, of which the following is a speciication. g

This invention has been patented to mein England under date of January19, 1897, No. 1,410.

In order that my invention may be clearly understood and more easilycarried into practical eect', I have appended hereunto a sheet ofdrawings, upon which. I have illustrated several examples of my methodsfor expanding tubes in their junctions or sockets.

The invention is illustrated in the accompanying drawings, in which-Figure lis a sectional view through two adjoining tubes of a bicycle,showing the tool in the position assumed just prior to expanding the endof one tube. Fig. 2 is a similar view after the completion of theexpanding operation. Fig. 3 is a View of 'a modified form.

Referring to Figs. 1 and 2, T represents the 4tube of a bicycle which isto be expanded within the socket S, and this is accomplished by the toolB, which has an enlargement or spherical face b at the end, which isforced into the mouth of the tube by the wedge-tool WV, movingapproximately at right angles or transversely to the tube to beexpanded.

Instead of a tool, as shown at B, I may use a ball b2, as shown in Fig.3.

Having now particularly described and ascertained the nature of mysaidinvention and in what manner the same is to be performed, I declare thatwhat I claim is-- 1. A device for expanding the end of a tube within asocket in cycle construction comprising a member having a spherical faceand a wedge adapted to move approximately at right angles to the tube tobe expanded to drive the rounded face within the tube end, substantiallyas described.

2. A device for expanding the ends of tubes within the sockets in cycleconstruction comprising a member having an enlargement or swell adaptedto enter the mouth of the tube to be expanded, and a wedge adapted to bedriven in beside said iirst member at approximately right angles to thetube to be expanded to force it against the tube end, substantially asdescribed.

kIn testimony that I claim the foregoing as my own I affix my name inthe presence of two witnesses.

EDWIN TAYLOR.
